Title: Method for controlling right and left screw-down locations in work roll shifting mill
Inventor: SHIRAISHI TOSHIICHI
IPC: B21B37/58
Filed: 1996-02-01
Abstract: PROBLEM TO BE SOLVED: To maintain the state of stable rolling over a long period even in such a case as a control method for correcting right and left screw-down locations based on the right and left asymmetrical components of a roll gap which are determined by the change of profile and shifting position with roll wear is hitherto proposed in a rolling mill whose work rolls are shiftable in the axial direction. SOLUTION: The asymmetrical components of the roll gap are calculated from the profiles of back-up rolls 3, 4 between which the work rolls 1, 2 are held and the shifting amounts of the work rolls 1, 2 and, by these calculated results, the right and left screw-down locations are corrected. That is, when the wear of the back-up rolls 3, 4 is gradually progressed, the right and left asymmetrical components of the roll gap are generated due to that. Then, by executing correction based on the asymmetrical, even when the changing of the work rolls is repeated, the generation of difference between the right and left thickness is suppressed and the state of stable rolling is maintained.

IPC: B23K26/351
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a novel method capable of highly precisely executing work for a green sheet stuck on a drum by dissolving a beam irradiating positional deviation caused by a drum ripple. SOLUTION: Before actual working is executed, actual angular velocities ω1 to ωn in each of rotational angles A1 to An of a drum to which a beam irradiating command is issued are detected while idling the drum to which a green sheet is stuck, and the difference between the detected angular velocities ω1 to ωn and a set angular velocity ω is obtained. When working is executed, based on the difference between the pre-detected angular velocities ω1 to ωn and the set angular velocity ω, the beam irradiating command is rather early issued in order to offset the difference of the angular velocity when the difference of the angular velocity is positive value, while the beam irradiating command is late issued in order to offset the difference of the angular velocity when the difference of the angular velocity is a negative value.
